Lipped seal

roundwith frameC-ring

Type C of large gap ultrahigh-pressure sealing components Performance and Purpose: 1.It is made up of sealing ring、fan-shaped supporting blocks and fan-shaped angles. It is mainly used in the pressure test of steel pipe by hydro-static testing machine. 2.Type C has more seal gap than Type D (refer to company’s former catalogue), the sealing components with same dimensions are applicable to a wider range of steel pipe range. 3.Lip Optimization: under peripheral pressure, the lip and groove surface fit more closely, and the higher the pressure, the better the lip sealing. 4.The fan-shaped supporters , in the premise of increasing the strength of the sealing ring, can shrink and expand in radial direction with the sealing ring. 5.It is applicable to the pressure testing of casing, tubing, natural gas pipe and other steel pipe. It has also been used in leak test of the steel pipe，welded joints and sealing for the ultrahigh pressure valve. Working conditions: Working pressure: ≤ 120 MPa Working temperature: -20℃～+80℃ Working medium: water, emulsion, hydraulic oil Material: Polyurethane
